My all time favorite hacked client is Obsidian, but the developer stopped updating it after 1.6.2. I personally hate Nodus because it tries too hard to put everything into one client, but it prefers quantity over quality, and that's almost never a good thing.
Any suggestions on other clients?
Added (1). Kinky looks pretty good, but the only download I found for it was 1.6.4:c
Kinky. I use it:3
Because of the new 1.7.2 features, hacking has become much harder to do. There are only a few 1.7.2 ones out there, and about only a few of them are worth trying. Nodus is not so bed, give it a shot. If you want to try out some other hacked clients head on over to http://www.wizardhax.com/ for some good ones.
PS. R.I.P obsidian. It was my favorate too

Please use it responsibly.
Weepcraft is a good client I have it. It probably has the most hacks in it have fun
